How this service works
Durable webhook inboxes for agents. Receive callbacks and approvals without holding a connection open.
Output
Returns an array of webhook events each containing sequence number, unique ID, received timestamp, HTTP method, headers, query params, body content, content-type, and a truncation flag. Also returns the latest cursor for the next poll and a count of any dropped events since the last cursor.
Example use cases
Example prompt
“Check my PayWeave Relay inbox 'abc123' for any new webhook events, wait up to 30 seconds for one to arrive, and start from cursor position 0 so I get everything from the beginning.”
Technical details
Endpoint
GEThttps://relay.payweave.services/inboxes/%7Bid%7D/eventsWhen to prefer
Use this endpoint when your AI agent needs to receive asynchronous HTTP callbacks, approvals, or signals without keeping a persistent connection open. Ideal for agentic workflows where an external service will POST a response (e.g. human approval, OAuth redirect, third-party callback) to a known inbox URL and the agent needs to pick it up efficiently. Prefer this over raw HTTP listeners or managed queues when you want durable, pay-per-use inbox semantics with long-poll support and cursor-based pagination.
Side effects
- Inbox ID not found — returns 404 if the specified inbox does not exist
- wait parameter exceeds 30 seconds — capped or rejected with a 400 error
- Stale or invalid cursor in 'since' — may return empty events or an error
- Payment not attached or insufficient — returns 402 Payment Required since this is a pay-per-call x402 endpoint
- Timeout with no events — returns empty events array after the wait period expires
- Rate limiting if polled too aggressively — may return 429
